The Practice of"Unity of Knowledge and Practice"in the Teaching of Analytical Chemistry:Taking the Determination of Total Nitrogen Content in Soil as an Example
Taking the determination of total nitrogen content in soil as an example,based on task-driven teaching,the"Kjeldahl Method"in the application of acid-base titration in the course of analytical chemistry,in series with the old knowledge of sampling and processing of analytical samples,error in analytical chemistry and data processing,etc.,by setting the task of decomposing and grading and"Learning by doing",the students are guided to apply the theoretical knowledge of the textbook to solve practical problems,and develop the students'ability of combining theory with practice as well as their ability of application,to realize"Unity of knowledge and practice",improve the comprehensive quality of students,and stimulate students'interest in learning.
